<span>An independent clause is a clause that can stand alone as a sentence (i.e., it expresses a complete thought). An independent clause, like all clauses, has a subject and verb. When there are no dependent clauses in the same sentence as an independent clause, the independent clause is a simple sentence.</span>
A little tricky but I think the answer is B because it seems more of a statistic then an opinion
I believe the correct answer is B. The modifier "wearing a blue dress" is placed far from the noun which is supposed to modify - Stacey. Such as it is, it could easily be attributed to another noun, the stage. It would seem that the stage was wearing a blue dress, rather than Stacey. This is easily fixable with a comma between "stage" and "wearing".
The C and D sentences are also a little bit awkward, but they don't contain a misplaced modifier.
